I’LATE LXIX. FIG. I. 
In England, the Black Grouse is most abundant in the 
northern counties, and is generally diffused over most 
parts of Scotland. Many experiments have been made to 
introduce it into those districts, further south, where it 
was not naturally indigenous, but for the most part with¬ 
out success, although attempted in situations which ap¬ 
pear in every way favourable, and similar to those in 
which they are naturally in great abundance. 
In habits, this species differs considerably from the 
next. Whilst the red grouse inhabits the most desolate 
and the wildest heaths, the Black Grouse frequents the 
borders of cultivation, breeding either amongst the heath 
or in recently planted ground, and sometimes in the 
hedge-rows. It lays from eight to ten eggs, usually much 
less strongly spotted than the plate, and differing con¬ 
siderably according to the locality in which they are 
found.
